Naphthalene is an aromatic compound.

Answer

To determine whether naphthalene is an aromatic compound, we can follow these steps:

### Step 1: Understand the Structure of Naphthalene
Naphthalene is a polycyclic aromatic hydrocarbon consisting of two fused benzene rings. Its molecular formula is C₁₀H₈.

### Step 2: Count the π Electrons
In naphthalene, there are a total of 10 π electrons. This can be determined by examining the double bonds in the structure. Each double bond contributes 2 π electrons, and there are 5 double bonds in total.

### Step 3: Apply Huckel's Rule
Huckel's rule states that for a compound to be aromatic, it must have a certain number of π electrons given by the formula:
\[ 4n + 2 \]
where \( n \) is a non-negative integer (0, 1, 2, ...).

### Step 4: Solve for n
We have 10 π electrons in naphthalene. Plugging this into Huckel's formula:
\[ 4n + 2 = 10 \]
Subtract 2 from both sides:
\[ 4n = 8 \]
Now, divide by 4:
\[ n = 2 \]

### Step 5: Check the Value of n
Since \( n \) is an integer (specifically, \( n = 2 \)), this satisfies Huckel's rule.

### Step 6: Conclusion
Since naphthalene has 10 π electrons and satisfies Huckel's rule, we conclude that naphthalene is indeed an aromatic compound.

### Final Answer
**True, naphthalene is an aromatic compound.**
